I am starting this thread to expand on multiwire discussion which was brought up in another post.
I use multiwire circuits all the time and I think they are a Godsend in making our jobs easier and neater. I too mark each set of hots by taping them to their corresponding neutral in the panel.
Recently I have thought up the idea of having my printshop make me up a roll of adhesive labels saying something like: "Caution: This system utilizes shared neutral conductors. Re-arrangement of breakers by unqualified persons could result in a fire hazard"
Has anyone thought of or done this? Any opinions?
As far as Joe Homeowner screwing it up, I see far worse almost daily. Just today I found a bathroom receptacle wired with some single lengths of old #18 stranded, tapped from a 20 amp circuit. I wonder how hot they'd get from a 1500 watt heater?
Any opinions on the labels?
